Fig. 2 in Diet shift of Red Belly Pacu Piaractus brachypomus (Cuvier, 1818) (Characiformes: Serrasalmidae), a Neotropical fish, in the Sepik-Ramu River Basin, Papua New Guinea
Fig. 2. Comparison of the relative contribution of food categories to the diet (% volume) of Piaractus brachypomus of introduced (Sepik River) and natural populations (Colombia: Tarapoto Lake and Caquetá River; Brazil: Tocantins River and Tucuruí Reservoir; Venezuela: Caura River). Food items included in each category are listed in Table 1. Category "Other" includes: mammals, arthropods, plant material of unknown origin, and debris (Sepik); detritus (Tarapoto); gravel (Caquetá FW). Abbreviations: FW, falling water season, LW, low water season; RW, rising water season; DS, downstream from reservoir; RS, reservoir.

Fig. 1. Map of sampling site and locations of comparative studies. Circles represent sites in the Amazon Basin (Colombia: Tarapoto Lake and Caquetá River; Brazil: Tocantins River). The triangle represents a site in the Orinoco Basin (Venezuela: Caura River). The star represents the sampling site at the lower Sepik River, Papua New Guinea (PNG).
Fig. 6 in The effect of structural enrichment in hatchery tanks on the morphology of two neotropical fish species
Fig. 6. Most important ecomorphological attributes for Brycon orbignyanus in the morphological differentiation among treatments, according to the ANOVA and the DCA, concomitantly. Treatments with a different letter above their ranges differed significantly.
Fig. 3 in The effect of structural enrichment in hatchery tanks on the morphology of two neotropical fish species
Fig. 3. Condition factors (CFs) for Prochilodus lineatus and Brycon orbignyanus. The ANOVA was significant for both species (p <0.0001), demonstrating significant differences among the treatments. The results of the Tukey tests specifying which CFs were different from each other is demonstrated by the letters A, B, and C. Different letters indicate significant differences among the treatments.
Fig. 5 in The effect of structural enrichment in hatchery tanks on the morphology of two neotropical fish species
Fig. 5. Most important ecomorphological attributes for Prochilodus lineatus in the morphological differentiation among treatments, according to the ANOVA and the DCA, concomitantly. Treatments with a different letter above their ranges differed significantly.
Fig. 7 in The effect of structural enrichment in hatchery tanks on the morphology of two neotropical fish species
Fig. 7. The log of the distance from the centroid plus 1 [log (DC+1)] for Prochilodus lineatus and Brycon orbignyanus. The ANOVA was significant for both species (p <0.0001), demonstrating significant differences among the treatments. The results of the Tukey tests, specifying which DCs were different from each other, are demonstrated by the letters A, B, and C. Different letters indicate significant differences among the treatments.
Fig. 4 in The effect of structural enrichment in hatchery tanks on the morphology of two neotropical fish species
Fig. 4. Projection of the four treatments [C = control; L = logs; M = macrophytes; and B = both (logs+macrophytes)] in the first two axes of the Principal Component Analysis for Prochilodus lineatus and for Brycon orbignyanus.
FIGURE 4 in Seeking for gaps in taxonomic descriptions of endemic fishes: a pathway to challenge the Linnean shortfall in a Neotropical basin
FIGURE 4 | Histograms of the year of endemic fish species descriptions according to the fluvial hierarchy of watercourses. Higher negative skewness (-3,18) in low order streams (first to third order, left histogram), and lower negative skewness (-2,57) in high order streams (seventh to ninth order, right histogram).
FIGURE 1 in Seeking for gaps in taxonomic descriptions of endemic fishes: a pathway to challenge the Linnean shortfall in a Neotropical basin
FIGURE 1 | Spatial distribution of localities where the holotype of endemic fish species was found in the Tocantins-Araguaia River basin (grey circles). The red circles delimit the transition zone between upper, middle, and lower sections of the basin.
